Van der Waals law calculator

Van der Waals equation describes fluids composed of particles that are attracted to each other and have a non-negligible volume. The pairwise attraction is called van der Walls force. The law was discovered by Johannes Diderik van der Waals, who later received the Nobel prize for his work on the equation of state for liquids and gases. The van der Waals equation is a modification of the ideal gas law that takes into account the non negligible size of the molecules and the attraction force between them and as a result better described the behavior of real fluids.
